Secondary design system for intelligent substation on basis of Excel

Abstract

The invention discloses a secondary design system for an intelligent substation on the basis of Excel. According to the technical problem to be solved, design personnel can finish primary and secondary design of the intelligent substation fast and conveniently. The system is arranged on a personal computer networking with a switch. The switch is connected with more than one computer terminals. An intelligent substation design paper module of the system is connected with a database module. The secondary design system is further provided with a secondary equipment calculation module and a secondary equipment analysis module. The secondary equipment analysis module is connected with the database module. The secondary equipment calculation module is connected with an Excel standard template and a parameter configuration file module. The parameter configuration file module is connected with a user interface module. Compared with the prior art, secondary equipment lists of the intelligent substation are output to the electric power bureau and used for bidding work of secondary equipment, a scheme primarily designed is fast guided into the normal design work of the intelligent substation, the design work efficiency of the intelligent substation is improved, and manpower waste is reduced.

Description

technical field [0001] The invention relates to a smart grid system, in particular to a secondary design system of a smart substation. Background technique [0002] China's smart grid has entered the stage of comprehensive construction, and infrastructure substations will be built according to smart substation standards. State Grid Corporation and China Southern Power Grid Corporation have issued relevant smart substation design specifications: "State Grid Corporation Enterprise Standard (Q / GDW394-2009): 330kV ~ 750kV Smart Substation Design Specification", "State Grid Corporation General Design for Power Transmission and Transformation Project 110 (66)-750kV Intelligent Substation Part", "Q / GDW 175-2008 Transformer, High Voltage Shunt Reactor and Busbar Protection and Auxiliary Device Standardized Design Specification", "110(66)kV~220kV Intelligent Substation Design Specification", "Guizhou Power Grid Digital Substation Technical Specifications", "Notice of the General Off...

AI Technical Summary

Problems solved by technology

[0003] The status quo of smart substation construction in the prior art is: the power company puts forward the design requirements for smart substations, and the design unit designs according to the design specifications of the region. different design specifications, different designers have different understandings of the specifications, resulting in deviations in the design work

2. There are many types of specifications, and designers cannot grasp them one by one, and it is easy to confuse the differences between various design specifications, resulting in design deviations

3. The design of smart substation is divided into preliminary design and formal design. The preliminary design is based on the user's needs, and the preliminary design plan will be reviewed by the user. After the user's review and modification, the formal design will start. Inherited and quickly transferred to the formal design work of the smart substation, the formal design work sometimes needs to be restarted, resulting in a huge waste of manpower
